使用handler(TypePattern)切入點(diǎn)。語法：
pointcut <pointcut name>(<any values to be picked uo>) : handler(<class>) ;
handler(TypePattern)切入點(diǎn)只支持vbefore()形式的通知。這意味著不能使用像around()這樣的通知來重寫catch塊的正常行為。

public aspect HandlerRecipe {
 pointcut myExceptionHandlerPointcut() : handler(ServiceException);
 before() : myExceptionHandlerPointcut() {
  System.out.println("------------ Aspect Advice Logic --------------");
  System.out.println("Signature: " + thisJoinPoint.getStaticPart().getSignature());
  System.out.println("Source Line: " + thisJoinPoint.getStaticPart().getSourceLocation());
  System.out.println("-----------------------------------------------");
 }
}


public class ServiceException extends Exception {

 /**
  * Create a new ServiceException with the specified message.
  * @param msg the detail message
  */
 public ServiceException(String msg) {
  super(msg);
 }

 /**
  * Create a new ServiceException with the specified message
  * and root cause.
  * @param msg the detail message
  * @param ex the root cause
  */
 public ServiceException(String msg, Throwable ex) {
  super(msg, ex);
 }
}

public class ExceptionClass {

 public void triggerMyException() throws ServiceException
    {
  ServiceException myException = new ServiceException("A service exception has occured");
       System.out.println("About to throw a ServiceException");
       throw myException;
    }
 /**
  * @param args
  */
 public static void main(String[] args) {
  ExceptionClass myObject = new ExceptionClass();
   try
       {
          myObject.triggerMyException();
       } catch (ServiceException me)
       {
          System.out.println("A ServiceException has been caught");
       }
 }

}

運(yùn)行結(jié)果：
About to throw a ServiceException
------------ Aspect Advice Logic --------------
Signature: catch(ServiceException)
Source Line: ExceptionClass.java:19
-----------------------------------------------
A ServiceException has been caught
